In my perfect scenario I visualize these lactose-free, gluten-free, earth-shoe types turning off all the lights in their house for an hour, and then when they go to turn them back on... nothing. Click-click. No light. They check with their neighbors. No light. No heat. After about a day, panic would set in. This would make a good sic-fi short story.
Libs like to play games of "let's feel good about ourselves", but they don't and can't live with the consequences of their actions.
